Introduced for 2004, Infiniti's large sport-utility vehicle was a slightly restyled premium version of the Armada wagon from parent-company Nissan. Seating up to eight, the QX56 came standard with such features as a power liftgate, wood/leather interior trim, 18-inch chrome wheels, and xenon headlights. It shared Armada's 5.6-liter V8 but had 315 horsepower--10 more than Nissan's SUV. A five-speed automatic with tow/haul mode was the sole transmission. The QX56 could have rear-wheel drive or four-wheel drive that included low-range gearing. The AWD system could be locked in rear-wheel drive, 4-wheel High, or 4-wheel Low; an "Auto" setting selected 2WD or 4WD as needed. Antilock four-wheel disc brakes, traction/antiskid control, and automatic load-leveling rear suspension were standard. Maximum towing capacity is 8900 pounds. Infiniti's SUV seated seven with second-row bucket seats, or eight with an available second-row bench. Second- and third-row seats folded flat. Front side airbags, curtain side airbags for all three seating rows, and a tire-pressure monitor were standard. Every QX56 had xenon headlights, a power liftgate, and wood/leather trim. Also included were heated front and second-row seats, power-adjustable pedals, a navigation system, and rear-obstacle detection. Options included satellite radio, DVD entertainment, and radar cruise control that was designed to maintain a set following distance. Also available was a camera that displayed a rear view on the navigation screen when the transmission was shifted into Reverse. Big-SUV competitors included the Cadillac Escalade, GMC Denali XL, and Toyota Land Cruiser.
